The first thing Mallory Rogers noticed was that she couldn’t keep a dry diaper on her daughter. She would change Addie and then 10 minutes later, she’d have to do it again. Six diapers for her 2-year-old every hour, which felt like some kind of Guinness World Record for moms. (Tanner, 7/12)

Two studies today in Pediatrics detail the health and economic benefits of routine childhood immunization in the United States. Both studies were led by scientists from RTI Health Solutions and Merck. One study examined the incidence of 14 vaccine-preventable illnesses with and without universally recommended vaccines for children 10 years and younger over 5 recent years. Routine immunization lowered the incidence of all studied diseases, from 17% for flu to 100% for diphtheria, Haemophilus influenzae type b (Hib), measles, mumps, polio, and rubella. These decreases correspond to more than 24 million averted cases of vaccine-targeted illnesses for the 2019 US population of 328 million people. (7/13)

For her birthday every October, Grace Gibson-Snyder and her family explore the Lamar Valley just inside the northern border of Yellowstone National Park. Carved long ago by meandering glaciers, the valley is home to bison and bald eagles, grizzly bears and gray wolves. Gibson-Snyder has seen them all. She calls it “my favorite place.” “I know how special it is to have this in my life,” said Gibson-Snyder, an 18-year-old from Missoula, Montana, “and I don’t want it to go away.” (Ehli, 7/14)
